Rio de Janeiro - Singapore's top paddler Feng Tianwei will not defend her Olympics singles medal, after losing to Japan's Ai Fukuhara in the quarter-finals on Tuesday morning (Brazil time).
The world No. 4 and second seed, who was widely expected to at least make the semi-finals, was beaten 4-0 (14-12, 11-8, 11-7, 11-5).
Feng said: "Fukuhara played way above my expectations today. Firstly, I was quite anxious on court and wasn't patient enough when my strategy and tactics didn't work."
Team-mate Yu Mengyu also lost her quarter-finals in her match against North Korean Kim Song I 4-2 (8-11, 11-6, 5-11, 6-11, 11-9, 6-11).
Kim is on a fairytale run to the final four, having already beaten the fourth seed Kasimi Ishikawa of Japan in her opening round. Yu's defeat means Singapore ends its campaign in the women's singles event.
Yu, who was reduced to tears after her loss, said: "I came close in my first Olympics. There is some regret."
Against an opponent she has an overwhelmingly superior 14-3 head-to-head record on the International Table Tennis Federation professional circuit, Feng had no answers on Tuesday. Fukuhara, on form and aggressive in her play, forced many errors from Feng's bat.
